A direct numerical simulation (DNS) of a planar jet with a second-order chemical reaction is performed using four different Schmidt number (Sc = 1, 2, 4, 8). Reactant A is contained in the jet flow and reactant B is contained in the ambient flow. The

In metal-anode batteries such as zinc, the concentration of metal ions in the electrolyte usually plays a significant role in the metal electrodeposition upon charging. This study aims to clarify the concentration of zincate ions near the zinc anode.

Mass transfer velocity kL across the wind-driven air–water interface was estimated at extremely high wind speeds (up to U10=70 m s−1) in a high-speed wind-wave tank by measuring changes in CO2 concentration in the water. In addition, the volume f

Effects of half delta-wing shaped vortex generators (VGs) on thermal diffusion of an axisymmetric jet are experimentally investigated. The basic experimental setup is same as that of our past study (Miura et al., 2015). Six VGs are equally arrayed ar
